In recent years, researchers have discovered numerous security flaws in some widely used Java implementations, including Oracle’s, which allow untrusted code to bypass the sandboxing mechanism, exposing users to malicious attacks.
In addition to language changes, significant changes have been made to the Java class library over the years, which has grown from a few hundred classes in JDK 1.0 to over three thousand in J2SE 5.0. Entire new APIs, such as Swing and Java 2D, have evolved, and many of the original JDK 1.0 classes and methods have been deprecated.

The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. A Java platform includes an execution engine (called a virtual machine), a compiler and a set of libraries; there may also be additional servers and alternative libraries that depend on the requirements. Java platforms have java developer course been implemented for a wide variety of hardware and operating systems with a view to enable Java programs to run identically on all of them. In addition, several languages have been designed to run natively on the JVM, including Clojure, Groovy, and Scala. Memory management is handled through integrated automatic garbage collection performed by the JVM.
